Abstract

Photovoltaik-Indachmodul mit einem Rahmen aus Polymerbeton mit Hinterlüftungsfunktion, dadurch gekennzeichnet, dass in den dargestellten Bereichen eine gute Hinterlüftung in dem Gußrahmen sichergestellt wird, indem große Flächen der Rückseite ausgenommen werden und so eine natürliche Luftzirkulation (Konvektion) hinter der Dacheindeckung gewährleistet wird (1). Weitere Lüftungsöffnungen an der vorderen Kante (5) begünstigen diese Konvektion zusätzlich.Photovoltaic roof module with a frame made of polymer concrete with ventilation function, characterized in that in the illustrated areas a good ventilation in the Gußrahmen is ensured by large areas of the back are excluded and so a natural air circulation (convection) is ensured behind the roofing (1 ). Further ventilation openings on the front edge (5) further promote this convection.

Description

Photovoltaik-Modul aus Polymerbeton und einem Glaslaminat mit 14 Photozellen, welche beispielsweise eine Leistung von 55 Watt bzw. 58 Watt vorweisen. Dieses Modul besitzt die Höhe von Dachziegeln des Typs „Nelskamp Nibra G10” und ist genau so lang wie fünf nebeneinander liegende Dachziegel.Photovoltaic module made of polymer concrete and a glass laminate with 14 photocells, which have, for example, a power of 55 watts and 58 watts respectively. This module has the height of "Nelskamp Nibra G10" tile and is exactly as long as five adjacent roof tiles.

Die Lösung einer Photovoltaik-Anlage als In-Dach-Lösung ist nicht neu. Aber andere Anbieter besitzen entweder eine Lösung für Rahmenmodule, oder sie besitzen eine Variante mit ebenen (glatten) Modulen. Beide Lösungen lassen sich optisch nicht der restlichen Dacheindeckung anpassen. Weiterhin benötigen andere Lösungen oftmals zusätzliche Hilfsmittel (z. B. Modulklemmen, Aluminiumprofile, Gummidichtungen usw.), um die Module auf dem Dach zu befestigen.The solution of a photovoltaic system as in-roof solution is not new. But other vendors have either a solution for frame modules, or they have a variant with flat (smooth) modules. Both solutions can not optically be adapted to the rest of the roofing. Further, other solutions often require additional resources (eg, module clamps, aluminum profiles, rubber seals, etc.) to secure the modules to the roof.

Viele In-Dach-Systeme besitzen keine ausreichende Hinterlüftung der Module. Im Schutzanspruch 1 wird dieses Problem durch Ausnehmungen an der Rückseite des Polymerbetonrahmens gelöst.Many in-roof systems do not have sufficient ventilation of the modules. In protection claim 1, this problem is solved by recesses on the back of the polymer concrete frame.

Die Photovoltaik-Module müssen über viele Jahre hinweg den äußeren Witterungen standhalten. Hierzu gehören Wind- und Schneelasten ebenso, wie Regen, Hagel und Luftfeuchtigkeit. Aus diesem Grund sind die im Schutzanspruch 2 festgehaltenen Merkmale wie umlaufende Auflagefläche des Glaslaminates eingebracht.The photovoltaic modules must withstand the outside weather for many years. These include wind and snow loads as well as rain, hail and humidity. For this reason, the recorded in the protection claim 2 features are introduced as circumferential bearing surface of the glass laminate.

Photovoltaik-Module stören besonders bei In-Dach-Lösungen die Optik der Dacheindeckung, da die Oberfläche der Dachpfannen verdeckt wird oder gegen komplett ebene Module ausgetauscht werden.Especially in in-roof solutions, photovoltaic modules disturb the appearance of the roofing, as the surface of the roof tiles is concealed or replaced by completely flat modules.

Aus diesem Grund bietet das „Genius Flat G” die Optik der Nelskamp Nibra G10 in den im Schutzanspruch 3 festgehaltenen Bereichen.For this reason, the "Genius Flat G" offers the appearance of the Nelskamp Nibra G10 in the areas held in the protection claim 3 areas.

Schutzanspruch 4 bezieht sich auf das Material Polymer-Mineralguss. Der Mineralguss bietet entscheidende Vorteile, wie z. B. die harte Bedachung, Formstabilität, hohe Bruchfestigkeit, gute Wärmeisolierung.Protection claim 4 refers to the material polymer-mineral casting. Mineral casting offers decisive advantages, such as: As the hard roofing, dimensional stability, high breaking strength, good thermal insulation.

Schutzanspruch 5 bezieht sich ähnlich wie Schutzanspruch 1 auf die Kühlung des PV-Moduls. Aus diesem Grund wurden kleine Öffnungen in der unteren Auflagefläche des Genius Flat eingelassen. Diese Öffnungen fördern zusätzlich zur natürlichen Konvektion zwischen Dacheindeckung und Dachdämmung den Abtransport der Wärme. Diese Öffnungen dienen bei Windstille oder Lage im Windschatten dafür, dass die Stauwärme zusätzlich abziehen kann und zum anderen bei Wind als zusätzlichen Einlass für kühle Luft.Protection claim 5 refers similar to protection claim 1 to the cooling of the PV module. For this reason, small openings were made in the bottom surface of the Genius Flat. These openings promote the removal of heat in addition to the natural convection between roofing and roof insulation. These openings serve in calm or position in the slipstream that the accumulation heat can additionally deduct and on the other hand in wind as an additional inlet for cool air.

Additional vents on the front edge ( 5 ) additionally favor this convection. Photovoltaik-Indachmodul mit einem Rahmen aus Polymerbeton mit Hinterlüftungsfunktion, dadurch gekennzeichnet, dass eine umlaufende Auflagefläche die Möglichkeit bietet, dass das Glaslaminat hohe Flächenlasten aufnehmen kann und diese gleichmäßig auf den Polymerbetonrahmen überträgt (2). Spannungsspitzen die zu einem Glasbruch oder Beschädigung des Laminats führen könnten, sind dadurch sicher ausgeschlossen. Zudem hat der Mehrkomponenten-Dicht- und -klebstoff die Funktion, die unterschiedlichen Längenausdehnungen von Glas und Polymerbeton über die Jahre hinweg zu kompensieren. Somit ist das eingelegte Photovoltaiklaminat ganzjährig gleichermaßen dicht und gegen Luftfeuchtigkeit und Wasser geschützt.Photovoltaic roof module with a frame made of polymer concrete with ventilation function, characterized in that a circumferential bearing surface offers the possibility that the glass laminate can absorb high surface loads and transfers them evenly to the polymer concrete frame ( 2 ). Stress peaks that could lead to glass breakage or damage to the laminate are thereby safely excluded. In addition, the multi-component sealant and adhesive has the function to compensate for the different length extensions of glass and polymer concrete over the years. Thus, the inserted photovoltaic laminate is year-round equally dense and protected against humidity and water.
